The document summarizes recommendations from the GBIF GSAP-NHC Task Group on improving the digitization and publication of natural history collection data. It recommends that GBIF facilitate discovery of non-digital collection resources, increase efficiency and quality of data capture, and improve global infrastructure for publishing digitized collection data. Specifically, it calls for GBIF to publicize non-digital metadata, assess the scale of undigitized specimens, support technological innovations for digitization, and strengthen hosting and identification of published data.
